Which bridge type is described as a structure with main towers, cable stays, and main girders, with cables inclined to the deck?

• A. Cable-Stayed Bridges
• B. Suspension Bridge
• C. Truss Bridge
• D. Arch Bridge

Answer: (A)

Cable-stayed bridges are built with tall towers and multiple cables that run directly from those towers to the deck, forming inclined stays. The deck rests on these stays, and the main girders carry the deck load while the stays transfer the load in tension up to the towers. The angled cables create a triangular, rigid framework that resists bending and deflection efficiently, allowing the span to be supported without the need for long hangers or a suspended deck.

This setup is distinct from a suspension bridge, where a pair of large main cables runs horizontally between towers and the deck is hung from vertical suspenders. It also differs from truss or arch bridges, which rely on truss elements or an arch shape to carry loads rather than inclined cable stays.
